After Professor Yorke earned his bachelors
degree from Columbia University in 1963, he came to the University
of Maryland for graduate studies, in part because of interdisciplinary
opportunities offered by the faculty of IPST. IPST is an Institute
established in 1950 and committed to interdisciplinary research in the
receiving his doctoral degree in 1966 in Mathematics, Yorke stayed
at the University as a member of IPST. Today he holds the title of
Distinguished University Professor and also is a member of the Mathematics and
Professor Yorke's current
range from chaos theory and weather prediction and genome
research to the population dynamics of the HIV/AIDS epidemic.
He is perhaps best known to
the general public for coining the mathematical term
"chaos" with T.Y. Li in a 1975 paper entitled
Three Implies Chaos". "Chaos" is a mathematical
concept in non-linear dynamics for systems that vary according to precise
deterministic laws but appear to behave in random fashion.
The University's chaos
one of the best in the world.
The objective of his chaos research is to describe those robust properties that
are common in the dynamics of physical, biological, and chemical systems.
Sometimes the phenomena can be described using rigorous mathematics, and
sometimes only phenomenological descriptions can be obtained from intensive
numerical studies. Most often, the research is a blend of numerical and
Professor Yorke has coauthored three books on chaos and a
monograph on gonorrhea epidemiology:
Prof. Yorke has supervised approximately
in the Depts. of Mathematics and Physics. Dr. Yorke's
includes a list of over 300 publications, many with abstracts,
and is available online, as is a short list of those
most frequently cited.
